THE O'FARRELL Government has suffered a major defeat at a state by-election on the weekend, with a record 27% swing back to Labor.
Triggered by the resignation of former state Sports Minister Graham Annesley, the by-election for Miranda was held on Saturday.
Former Labor MP Barry Collier, who previously held the seat between 1999 and 2011, won the seat with a margin of nearly 4000 votes (two-candidate preferred) in the 39,753 count on Sunday.
The state electorate, which sits inside Federal Immigration Minister Scott Morrison's Cook electorate, was a likely conservative victory, had it not been for Mr Collier's return.
Mr Collier, who resigned at Labor's NSW defeat in 2011, told ABC that local issues were crucial to his victory.
The contest saw Mr Collier beat his five competitors, receiving 18,511 of the first preference vote, of a total 40,656 vote cast.
